five more marches. Determined our latitude by
observations on March 22, and again to-day, March
25. A copy of the observations and computations is
herewith enclosed. Results of observations were as
follows: Latitude at noon, March 22, 85 deg. 48'
north. Latitude at noon, March 25, 86 deg. 38' north.
Distance made good in three marches, fifty minutes
of latitude, an average of sixteen and two-thirds
nautical miles per march. The weather is fine,
going good and improving each day.

With a sad heart I went to my cabin on the _Roosevelt_. Notwithstanding
the good fortune with which we had accomplished the return, the death of
Marvin emphasized the danger to which we had all been subjected, for
there was not one of us but had been in the water of a lead at some time
during the journey.

Despite the mental depression that resulted from this terrible news
about poor Marvin, for twenty-four hours after my return I felt
physically as fit as ever and ready to hit the trail again if necessary.
But at the end of twenty-four hours the reaction came, and it came with
a bump. It was, of course, the inevitable result of complete change of
diet and atmosphere, and the substitution of inaction in place of
incessant effort. I had no energy or ambition for anything. Scarcely
could I stop sleeping long enough to eat, or eating long enough to
sleep. My ravenous appetite was not the result of hunger or short
rations, for we had all had plenty to eat on the return from the Pole.
It was merely because none of the ship's food seemed to have the
satisfying effect of pemmican, and I could not seem to hold enough to
satisfy my appetite. However, I knew better than to gorge myself and
compromised by eating not much at a time, but at frequent intervals.

Oddly enough, this time there was no swelling of the feet or ankles and
in three or four days we all began to feel like ourselves. Anyone who
looks at the contrasted pictures of the Eskimos, taken before and after
the sledge trip, will realize, perhaps, something of the physical strain
of a journey to the Pole and back, and will read into the day-by-day
narrative of our progress all the details of soul-racking labor and
exhaustion which at the time we had been oblig
